题目: 根据逆波兰表示法,求表达式的值. 有效的运算符包括 +, -, *, / .每个运算对象可以是整数,也可以是另一个逆波兰表达式. Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. 说明: 整数除法只保留整数部分. 给定逆…
Evaluate the value of an arithmetic expression in Reverse Polish Notation. Valid operators are +, -, *, /. Each operand may be an integer or another expression. Note: Division between two integers should truncate toward zero. The given RPN expression…
利用栈实现算术表达式求值(Java语言描述) 算术表达式求值是栈的典型应用,自己写栈,实现Java栈算术表达式求值,涉及栈,编译原理方面的知识.声明:部分代码参考自茫茫大海的专栏. 链栈的实现: package 算数表达式求值; public class Stack<T> { //节点类 public class Node{ public T data; public Node next; public Node(){} public Node(T data,Node next){ this.…
